目前我们的小型及线材轧机大多数是横列式传统结构的轧机,其机架是铸造的开口式或闭口式的,有压下装置,轧辊轴承为胶木瓦开式轴承,轧机的刚度比较差,用这种轧机很难生产出高精度的产品。 At present, most of our small and wire rolling mills are traverse conventional mill, the frame is cast open or closed, with the pressure device, the roller bearing is a bakelite open bearing, the stiffness of the mill is relatively poor, It is difficult to produce high-precision products with this kind of rolling mill.
